Mercedes EQS Major Upgrade Revealed with Persistent Issue Remains

Mercedes-Benz EQS Gets Major Refresh for Canadian Drivers

Mercedes-Benz has unveiled a significant overhaul of its flagship electric sedan, the EQS, bringing substantial upgrades that could appeal to Canadian EV enthusiasts. Slated to arrive in Canada in the latter half of 2026 as a 2027 model-year vehicle, the refreshed EQS promises enhanced performance, new technology, and improved aesthetics.

Platform and Charging Upgrades

One of the most notable improvements is the upgrade to an 800-volt platform, up from 400 volts. This enhancement allows the EQS to charge at a peak rate of 350 kilowatts, surpassing even the new electric GLC, which tops out at 330 kW. On an 800-volt charging station, drivers can add approximately 320 kilometres of range in just 10 minutes. For those using a 400-volt charger, the maximum charging speed is capped at 175 kW.

Extended Range and Efficiency

The refreshed EQS now features a larger 122-kilowatt-hour battery, up from 118 kWh, and includes a two-speed transmission on the rear motor for improved efficiency. These changes result in the EQS becoming Mercedes' longest-range EV, with a claimed WLTP range of 925 kilometres for the single-motor EQS 450+ variant. While WLTP figures tend to be optimistic, Canadian drivers can expect impressive real-world ranges.

Innovative Steering System

An optional steer-by-wire system replaces the traditional steering wheel with a yoke, reducing the amount of steering lock required and increasing rear steering angle from 4.5 to 10 degrees. This enhancement makes the vehicle exceptionally manoeuvrable. The steer-by-wire system can be enjoyed independently of the rear steering upgrade, similar to the previous EQS model. Early testers report a sharp, natural, and effortless driving experience with this new system.

Enhanced Regenerative Braking

The EQS also boasts more powerful regenerative brakes, capable of recovering energy at up to 385 kilowatts. Mercedes indicates that, like the GLC EV—where motors handle 99% of braking—friction brakes play a minimal role in the EQS, maximising energy recovery.

Advanced Infotainment and Driver Assistance

Running on the new MB.OS operating system and featuring a 55-inch ‘Hyperscreen’, the EQS incorporates multi-agent AI, Google Maps integration, and over-the-air updates—features already seen in the CLA and GLC. The driver assistance systems have been upgraded with 27 sensors and cameras, offering optional obstacle avoidance capabilities.

Aesthetic Refreshes

Visually, the new EQS sports a revised front end with a more pronounced faux grille and redesigned hood. The daytime running lights now feature the Mercedes star and upgraded Digital Light technology, providing better illumination while using 50% less power. The rear lights include a new spiral-like LED element that enhances the vehicle's width and luxurious appearance.

Additional Comfort and Safety Features

Heated seatbelts, previously exclusive to the S-Class, will be available on the revised EQS. Mercedes highlights that these not only enhance comfort on cold days but also improve safety by encouraging occupants to remove thick winter jackets, allowing seatbelts and other safety systems to function more effectively in the event of an accident.

Canadian Considerations

For Canadian buyers, it's important to note the availability of provincial rebates and federal iZEV incentives, which can significantly reduce the final purchase price. While specific Canadian pricing has yet to be announced, these incentives could make the luxurious EQS more accessible.

Final Thoughts

The comprehensive updates to the Mercedes-Benz EQS—ranging from its advanced charging capabilities to its innovative steering system and enhanced safety features—position it as a cutting-edge electric vehicle. Despite minor visual changes that retain the original's distinctive shape, the improved performance and technology make the refreshed EQS a compelling option for Canadian drivers seeking a premium electric sedan.
